Mobile internet is growing at an incredible rate and as we can see from the data above, mobile experience is about 1.5x slower than desktop experience. That’s a very big difference, and that is even taking into account that many popular sites are already optimizing for the mobile visitor: fewer resources, smaller resources, and smarter caching strategies.
The following interactive world map presents the page load times for desktop in seconds for the complete list of countries with enough samples for accurate measurement:
The following map presents the corresponding data for mobile.

As a result, the country aggregates listed above depend on all those factors as well.
